Why I can not remove chars in label?

Question

I try label1.Text.Remove(1,2); but it doesn't work.

Can anyone help me?

Answer 1

Remove returns new string, does not modify current one, so you need to assign it to label:

label1.Text = label1.Text.Remove(1,2);

Answer 2

label1.Text is a string and strings are immutable (they cannot change). Think of it as an array of chars. You can't resize arrays without asking for new memory.

string.Remove returns a new, modified string. Simply do label1.Text = label1.Text.Remove(1,2);
